Reply #1 - say fc (feature class) is used as input to GALayerToPoints and output is fc2 - then AddField to fc - CalculateField from fc2 to fc - and repeat Reply #2 - the GA layer, in the TOC of ArcMap, can be saved to a .lyr file using SaveToLayerFile, or - if they (GALayers) are stored as .xml files, then use CreateGeostatisticalLayer tool Steve ...

Use the Dice tool (http://resources.arcgis.com/en/help/main/10.1/index.html#//001700000037000000) ... View more

I�??m afraid to say that I am unable to reproduce this. The only thing that we can think could happen is the following; many Geostat methods are multi-threaded (http://resources.arcgis.com/en/help/main/10.1/index.html#/Parallel_processing_with_multiple_CPUs/0031000000q5000000/) and what could be happening is that one thread is still calculating and a parameter is changed which means that that thread should be killed and a new one fired off. One way, and I know that K Bessel takes a long time to process, is to wait for the model to finish updating before a parameter is changed. ... View more

or... - set the processing extent around the pixels of interest - and also set SnapRaster=your input raster - RasterToPoint - edit the attributes (of the points) - PointToRaster and use the same cell size and extent as your original raster - use IsNull and Con to "insert" the changed raster into your original raster Note that RasterToPoint works with integer, floating point or string data. -Steve ...

If you are only interested in the area then you can run the IsNull tool, open the attribute table which will have 0 and a count and 1 and a count. The count for 0 is the number of cells that are not nodata. Multiply this by the squared cell size. Steve ... View more

Do you have Service Pack 1 installed? What Operating System are you running? Can you run other Spatial Analyst tools? Can the same data be used in Natural Neighbor interpolation? Have you rebooted your machine recently? Thanks Steve ... View more

can you send me the data ([email protected]) and the steps that you are following? ... View more

Brian I'm sorry to hear this. Some questions: - are you doing Areal Interpolation and do you have Service Pack 1 installed? - what Operating system are you using? Thanks Steve ... View more

They key to this discussion is the version of ArcGIS. Prior to ArcGIS 10 all the rasters are processed as grids and then converted to your raster format and all feature classes are written to shapefile and then finally converted to your format. So if you are using pre 10, your .tif will be converted to grid prior to RasterToPolygon doing it's thing. In ArcGIS 10 we process the data in it's native format. -Steve ... View more

You need an a priori raster as input. Please see the tool's help. To ignore values, set the pixel values (in the input raster) to zero or nodata. Do you have a Geostatistical Analyst license and have you checked it out in ArcMap? Steve ... View more

It is not supported for Geostatistical layers. You could send your output to a raster and then reclass the raster and convert that to polygons  (or use Filled Contours from http://blogs.esri.com/esri/arcgis/2013/01/17/introducing-the-spatial-analyst-supplemental-tools/). Steve ... View more
